- Here we try to fix an original Xbox power issue.
Parts replaced : Q901 1n60b FET , R901 22 ohm , R902 47k ohm, Q902 Pn2222A = NPS2222A, ZD902 18 volt Zener
The screen shot i showed with R902 is wrong, above is correct list of parts and their location

Youre an absolute master, its been a pleasure to watch the 38 minutes. Thanks for sharing
I'm going to do more videos soon, thankyou ☺️
Gracias por este gran vídeo, es de los poquísimos que realmente tiene utilidad. Gracias nuevamente.
thank you very much for this very educational video! I'll find it just because today my xbox died (hear a pop), inspection of psu and seen burned R902 so probably same defect! I'll.going to replace resistors, zener and transistors and let you know if come back to life!
Thank you this video is very helpful
Useful. Thank you!
Mad skills with the desoldering braid
I've used to for a long time
Is there any chance you could help convert a 220v to 110v for use in NTSC regions? I know it’s possible, but don’t have a clue on what parts to swap out.
Cool. The power supply you have is a bit different looking than the U.S. spec one, so recognizing the components between the two is a bit confusing. I know you don’t endorse just anyone tackling repairs on these power supplies, so I don’t blame you if you don’t answer my question. Looks like you have a white jumper wire going across the filter capacitor to the green fuse or resistor where mine has a grey, square resistor or capacitor that says 250vac. 310vac, .47 uf. It doesn’t look burnt on the bottom. Anyway, my question is… How does discharging the capacitor with the resistor not damage it; even though the power is disconnected? Thank you!
really nice tutorial ! i'm french and i have understand the tallest lines... my problem is not same on my xbox, but i follow your method to find who is faulty... i hope i will find ! my model is more simple than yours.
The repair method I did I use on most smps . I've fixed hundreds I'm a TV tech
Hi great tutorial. Yours is the best I have seen. My Xbox clicks when I push on button and does not turn on. Can i also use the omega setting and check each component to see if there is resistance?
Yes no problem, just takes a little practice 😉
Sorry to bother you about a Xbox PSU question. I've got an Xbox which stopped turning on, traced it down to the PSU and the high voltage side.
I actually have the 3.3V standby voltage and can see the opto is triggered (PS_ON floating; HV side of the opto is 5V, PS_ON connected to the 3.3V, opto is then ~130mV) but not sure why I'm not getting any output from the low of the transformer. I strongly suspect it might have something to do with the chopper circuit but I'm not sure exactly what is wrong. There is voltage (330V) on the main chopper leg, 532mV on the leg closest to the bulk cap with the last leg showing 0V. Could it be that transistor? Since there is no external signs of a problem but there was essentially some black dust on the main leg. If so, do you know where to get one? Searching for the part number, I couldn't find anything.
Thanks for any help.
Give me the part no on it, check for open cct feed resistors, check any diodes for shorts on secondary, 12volt rail comes up from feedback from mainboard power on
Thks
Dave
Hiya, did you end up getting it fixed? I have a similar problem and checked what Dave told you to check, but still nothing comes on the 12v rail. I realize our two scenarios might be different, but maybe your fix might spark new ideas. Thanks!
Hey I got a og xbox it flashes orange has no video audio output and hard drive doesn't power on any clue how to fix it?
شكرا لك تحياتي لك على الموضوع الجميل
I'm a beginner at this and I have an XBOX which I'm pretty sure I shorted somehow.
Are there safer reliable ways for checking continuity rather than plugging it into the wall?
Can just run the meter over looking for shorts, however it's not efficient method, it's ok to test bridge rectifier etc, any point after the main chopper transformer is safe as low voltages, I'd say you could tape up the primary cct so you can't access the Ac voltages
Thks
Dave
Also, you don't have your meter on Ohms when power is connected, it's set to read voltages, you can damage your multimeter
Thks
Dave
@@SuperDavidcass thank you
Great video! I got mine booted up, but after playing for a while I noticed the PSU is starting to heat up quite a bit. It is the secondary side transformer in the middle that heats up the most. Caps after it looked fine, but will try to replace them. Maybe they are a bit dried up, so it causes excess load??
Transformer shouldn't get that warm
@@SuperDavidcass yep. Something is consuming it too much when playing a game. It is fine in idle. No clear idea how to debug.
Were are you based? i have 2 psu that I'm sure are dead they are the Foxlink Model FTPS-0002
REV F was wondering if you can help fix them?
Ballarat, Victoria
What can i use as a replacement transistor at the first heat sink, i accidentally blew mine up, power supply is the same one you are working on, great video if you have downer boards
Aliexpress.com for parts
If you still need I can check replacement
Hey bud love your work and how you figured how to fix that power supply. I have the same one that doesn’t wanna turn on. Would like to pay you for fixing mine. We’re you located. 👍🏼 would like to hear from you.
I'm in ballarat, you can buy aftermarket power supply's, cheap, we did this one to show that anything can be fixed
where can i find that? thanks@@SuperDavidcass
If you checked the voltage on the large capacitor as you did at 6:00 and it had a voltage lower than expected, but did have a voltage, what would you test next?
I would check dc voltage on chopper transistor
@@SuperDavidcass Ok I think I have that solved, but now my 12v rail is fluctuating between 7 and 8 volts. I've tried replacing the capacitors and checked the resistors, do you think it would be the transistors?
Hello,i have simmilar model to this power supply and i have a weird problem.
When power supply is plugged in,it makes "buzzing" sound and i cannot launch Xbox.
But when i heat the mechanical part of the heatsink with soldering iron Xbox starts working again and it works for hours.
But when i turn it off and wait for 5-10 minutes to cool down,it doesnt work and is buzzing again.
Some people suggested it may be a faulty capacitor exposed to radiated heat,dry solder or cracked track(but tracks are okay)
What do you think sir?
Will be caps normally if heat works, replace most small electro capacitors
@@SuperDavidcass I replaced one electro capacitor and everything is fine now,thank you for advice :)
@@spartalmao7177 yes, we used to fix a lot of television with same faults, we used to heat board with a hairdryer, then use freeze spray to find the caps
Got the same problem with a xbox. Already took a look at the board and I spotted an area that looks like a burn mark next to a soldering joint that seemed cracked. I re-did the solder joint and a few next to it and cleaned up the area ... still, no power.
You need to measure voltages to see where the cct stops and starts
Any idea how to fix it if its reading 160V ik yous is reading 300+ V i assume this is the issue im having with my xbox having a green and red flashing light
Green and Red flashing is normally hard drive problem, are you on 240 volt or 120 volt mains power

Dave
So i hooked up my old xbox that's been in storage for years and as soon as i turned it on it didn't show any lights, after 5 seconds something blew, i think it was a leaked a capacitor because the power supply looks ok, no burning marks or anything, but i really don't know much about electronics so i couldn't tell, now i don't know what to do lol
anyone know whats up with the white gunk?
So what if u got standby n main 12v but only until a load is pulled and it falls off n shuts down?
Idd say other mainboard problems, idd say idd would try another external 12 volt supply to see if that holds, if it gets loaded down its mainboard, else the 12 volt power supply in th xbox isn't able to sustain current flow so it's the power supplybin the xbox still
Thks
Dave
Please HELP...I plugged my 110v XBOX to 240v and of course it stop working....which part of the power supply should i change ?
You can buy the whole power supply very cheap, we did the video to show process on how to fix SMPS
Thks Dave
So I replaced my motherboard with a whole refurbished board (new caps thermal paste etc. I paid 80$ for it) because my old was eaten through by acid and the power button didnt work. Now with the new board the power button works...but it cycles power every few seconds and then flashes red and green. Can a power supply unit thats going bad cause the system failure lights to appear?
Ho, I know why, the eeprom chip on board is locked to the hdd, have to swap eeproms over should fix this, same happens if you swap hdd around. Another way is to replaced the hdd with a new hdd and a modchip
Thks
Dave
In other terms you should of got the motherboard with the matching locked hdd
@@SuperDavidcass well it came with a hard drive that was already paired with the motherboard though. Could a faulty PSU cause the system failure (red and green lights) as well? I scraped off some white adhesive on my power supply and noticed a capacitor was bulging.
@TheDekuScrub no idd say it's hdd not paired, more likely, it's a fast job to use old hdd, swap thec8 leg eeprom chip over from old board
@@SuperDavidcass Hmmm alrighty I will try that thanks 🙏🏻 I already ordered a refurbished psu 🤦 all good though needs replacing anyways
@@SuperDavidcass what side of board is that on? I have the 1.4/1.5 focus revision
hello can u help me ? i have an v1.2 og xbox with foxlink power supply 220V The main capacitor 400V 180uf is bulging after i replace it with the new one its bulging again and again ,pls help
oh yea and theres no sign of burn component everything looks clean
That is very weird, how long did ot take to bulge again
Maybe i turn on 3 to 4 times and then the capacitor bulging again and then no power again
can I replace 1n60b with a FQU1N60C ? I cannot understand what are the differences
Idd say same, you can look up the specs for each using datasheercatalog website
Thks
Dave
@@SuperDavidcass on datasheets the FQU1N60C has lower current values: drain current 1A vs 1.4A, 28W power dissipation vs 35W and a Rds of 9.3 vs 7 Ohm
Its always safe to use a higher rated device not lower
Thk Dave's
Ps, make sure same package, some may be fully insulated, others not
Hi Dave, changed all the components you have mentioned and also D902 that was shorted (replaced with a bigger 1N5408) but still nothing. Any hints on what can I check?
Great video. I have a very similar PSU (Delta DPSN-96AP-1) that was completely burnout. I've replaced the burned components, but each time I connect the PSU, the R901 resistor (fusible resistor) opens up, and I cannot find the problem...This is way to complex....and I cannot even find a schematic for the PSU, so I will just replace it....
You got a short other side of the resistor,
I don't need a schematic cause I'm a Television tech and have fixed thousands of power supply's, so I'm used to it , double check diodes
Thks Dave
Its got a short other side of that resistor
What is "Shizugawa"?
Its a type of soup
Is 300 volts too much for this Xbox?
Input ac or dc reading on main filter cap ?
plz help me i got same power supply not working same resistor is burned i cant find parts tell me to Value of that resistor and value of that transister too
I put in description for you just now
Thks

u didnt mention zd902

Seems you had to re-upload you video...to answer your question Melb South East.
Yes I had some edits on it, I'm in ballarat, these videos I do for my subscribers, normally it's not worth fixing these, my cust paid $48 all up
@@SuperDavidcass Thanks. I have an Oynkio reciever that I have been thinking about getting fixed (center channel is not working anymore). Is that something would be able to fix?
@@CarsAndGadgetsAu been doing Audio many years, unfortunately no longer do Audio
Done hundreds of Ampliers
@@CarsAndGadgetsAu you can check dc voltages same way, or we normally use a signal tracer
It's nzrhyno the error code is system error E1O2 10070 C02 8B060008
Ok, anything else comes up on screen, ie
Reset, software update
